linux主机更换网卡，名称自动变成其他名称，mac地址没自动更新

 

表现：

# ifconfig|more

eth2      Link encap:Ethernet  HWaddr 00:50:56:21:47:F4 

          inet addr:192.168.0.103  Bcast:192.168.0.255  Mask:255.255.255

          inet6 addr: fe80::250:56ff:fe21:47f4/64 Scope:Link

# cat ifcfg-eth0

DEVICE=eth0

TYPE=Ethernet

ONBOOT=yes

NM_CONTROLLED=yes

BOOTPROTO=static

IPADDR=192.168.0.103

netmask=255.255.255.0

gateway=192.168.0.1

 

 

实际MAC地址是：

00:50:56:21:47:F4

 

修正：

# cd /etc/udev/rules.d/

# vi 70-persistent-net.rules

clip_image002

 

重启操作系统

 

网卡名变回eth0
